Clinical trials in males are currently ongoing. I would expect the vaccine to be approved for males in the next year or two.
I would administer this vaccine to my children in a heartbeat. I want them to avoid sex until marriage but I can in no way influence the men they will marry and what they will do before marriage (I have known many men who slept arround only to then get religious and become moral, but spiritual repentence does not get rid of microbes).
I believe it is child abuse not to give your children this vaccine.
